Pop-up cafes are a popular trend these days. In January an unusual version appeared in Los Angeles. It was a pop-up dog cafe. The temporary eatery featured a bevy of friendly canines from local shelters seeking forever homes among the patrons. Customers paid a fee of $15 or $20 to get in, have a bite and a sip, and revel in an abundance of dog wiggles, wet noses, and warm tongues.
